Until Graphene OS is allowed on different phones, then I'll consider. At some point they're gonna have to move to a different phone model.
My complaint with Lineage OS (that no one seems to talk about for some reason) is the requirements you gotta go through to get the exact phone in order to install them directly, hence one reason why I got the Teracube. Or some of these other OS system requirements, buying a phone for it is just not possible due to availability issues.
